Another object of the invention. is to pro Vide a means whereby bad beans may be pickedout of a supply of. beans without l manually handling the beans.

A further object of the invention to provide a means for picking the badbeans out of a supply of beans which willmake it possible to take; only one bean at a time.

to provide a device whereby badbeans may be picked outof a supply of beans'by suction.

And a tion is to provide a device for picking bad beans out of a supply of beans, which of a simple and economical construction.

With these ends in view, the invention embodies a continuous belt, means for driving the said belt, a hopper upon the said belt, pneumatic tubes with spring cups at their outer ends, and means for operating the conveyer'and causing suction in the tube.

Other features and advantages of the in vention will appear from the following description, taken in connection with the drawings, wherein:

Figure 1 is a cross section through the device. v

Figure 2 is an end view of the device. Figure 3 is a part section similar to the section shown in nate arrangement for driving the conveyer. Figure 4: is a plan view of the device withthe hopper omitted. Figure 5 is a detail showing one of the spring cups for picking up the beans.

In the drawings I have shown my devlce as it would be constructed wherein numeral 1 indicates the conveyer upon which the beans are fed to be picked, numeral 2 the fan for creating the suction, and numeral 3 the frame.

The conveyer 1 isformed with a' head pulley land a tail pulley 5 which are mounted on shafts 6 and 7 between the sides of the frame and the upper part of the conveyer is provided with a table 8 over which the upper part passes and which forms a backing so that a pressuremay readily be ex A still further objectof the invention is Si-.111 lat e ob ect? of the'iaven? for feeding beans Figure 1, showing an altererted upon the conveyer. Theshaft-G extends beyond the casing and has a pulley 9 on its outer endv which is driven from a pulley 10 on ashaft 11 by abelt 12. Theshaft '11 is provided ,with offset portions 13 and 14 thereby forming :a crankshaft and the PATENT OF ICE- a offset portions'areconnected topedals'15 and lfiby. rods 17 and 18. .The pedal s'are pivotally supported on a rod 19 and it will be observed that as the pedals are moved upward and downward, they will rotate the 1 shaft 11 and this-shaft will in turn operate the conveyer. It willbe seen that the conveyer may thereforebe operatedat any convenient speed and the speed may be varied. to accommodate the operator.

The fan 2 may b f. any sultable design and may, be 'arrangedin any suitable man- The suction opening of the fan is con-f; a tube 20 to a Y .21 and both ner. nected by v branches of the Y -are' connected to flexible tubes 22 whi h areprowded with spring cups 23 at their outer ends. J The cups are Figure 5 with tubes 24' having clips 25 at one side upon which formed as shown in the thumb may be placed as the device is held somewhat similar to a pencil between thethumb and forefinger and the lower end is provided with a spring 26 which extends slightly beyond the end of the tube. It will be observedthat as thecups 23 are placed over a bean and pressed downward, the suc- TYO tion will pass through the coils of the spring until the cup is pushed downward and when the spring is compressed, the suctionwill immediately and through the fan from where it may drop into abag cated by the numeral 27. The shaft of the fan 2 may be'provided with a pulley 28 which is driven by a pulley 29 on a motor 30 by abelt 31. It will be observed that as the motor is started, the fan will create a continuous suction in the tubes 22.

It is understood that any suitable speed ratio may be obtained between the conveyer and the motor by changing the I sizes of the gears or pulleys. g

It will be understood that changes may be made in the construction without de-' parting from the spirit of the invention.

The construction will be readily understood from the foregoing description: To use the device, itma-y be assembled in any suitable frame, Which in the design shown, is indicated by thefnuine-ral 3 provided portion 37 hopper 38 and legs 39 upon which the portion 87 is sup potted. "The-hopper 38 i'sjprovi-ded With an adjustable ba-flie 40 so that the size of the outlet thereof may readily adjiisted to 3 control the amount of beans that-pass upon the coniieyr and the for-Ward legs '39 of the ceiving. the dbjects fioih the l'efiei' end of frame may be providedwith sli-vda'ble' bars 41 which are held in thum" screwed-2' so that the forward end ofthe device may be incline of the cont eye'r so that the device may be used for peas or the like.
